CONTAINER.

lApplication med October 25, 1922. Serial No. 596,699.

My invention relates in general to cans of the tear-open type and moreparticularly to those in which a tearing strip is formed by score linesin the body beneath the top, and a l lseparate collar, or neck member,provided on l A further object of the invention is the pro-` vision ofan interior collar can of this character in which special sealing meansis em- ,ployed in addition to the frictional it of the parts to form aneffective and complete seal for the purpose stated. Another ob]ect ofthe invention is the provision of a process of assembling cansl of thischaracter which results in a tighter joint between the collar member andcan body than has heretofore been possible. 'y l Other objects andadvantages of the invention will be apparent as it is better understoodfrom the following description, which, taken in connection with theaccompanying drawings discloses a preferred embodiment thereof.` i

Referring to the drawings, v Figure 1 is a side elevation, 'partly insection, of a container in which my invention is embodied;

Fig. 2 is a partial vertical section,.somewhat enlarged, showing theinterior of the can body prior to the positioning of the collar orsupplementary wall part;

Fig. 3 is a similar section showing the interior collar and can coverassembled; and

Fig. 4 is an enlarged horizontal section showlng the relativearrangement of the locking seams formed in the can body and collar andshowing the cement in the spaces between said parts. The can shown inthe drawings fof the purpose of illustration, comprises a body 11 havinga bottom end 12 and a cover 13 secured thereto in a double seam 14,forming an hermetically sealed container. The body is of cylindricalform, the edges of the body blank being joined in aside seam 15, whiclis formed on the exterior ofthe body wal so that a flush inner surfaceis presented for liquid-tight engagement with aninterior collar or aband 16.

aid collar has its edges joined in an inwardly extending seam 17, thusforming a flush outer surface adapted for tight frictional engagementwith the inner surface of the body wall. The body is interiorly scoredat 18 and 19 to set of a tearing strip 21, which is provided with atongue 22 extending from a lapped portion of the side seam and adaptedfor engagement by a key for removal of the strip.

Said strip is diagonally scored, as indicated at 23, to facilitate thetearing of the strip upon \thelines 18 and 19, the tear being directedback to said line by this diagonal scoring in the event that, foranycause, it is directed away therefrom. n

Upon opening a can of this character con- `taining liquid extendin abovethe level of the tearing strip score hnes, there would be danger of thecontents spilling, with resultant loss and inconvenience to theconsumer, unless prevented by the inner band or collar. I, therefore,provide means for obtaining a tight seal between said collar and theinner face of the body, which the liquid between said odyn and the lowerpart of the collar. The said collarl, it will be understood, is securedbeneath the tearing stri and extends thereabove to provide a shoul erupon which the severed top of the can may be positioned .as a slipclosure. The

formation of the body and mterior collar,

as vheretofore described, permits a tight frictional it between saidmembers, which, in a prevents leakage of rangement of the \inner surfaceof'the can body beneath the score line 19, which, upon forcing thecollar 16 ldownwardly in the can, collects in a ljing 25 at the loweredge thereof, and said cement positively secures the collar to thesurface of the body, it being noted that said collar is turned inwardlyat its lower edge 26 and also att-he upper edge 27.

' It sometimes occurs that there is a sllght space, or crevice,indicated byI the reference character 28, at the point of bend of theside seam 15, or the seam 17 in the collar and when said collar is sopositioned, this space is filled by cement, as shown in Fig. 4, and theseal between said parts thus rendered more effective.

An important result which I secure by my invention is to insure arr evenand level severance of the tearing strip around the body on the linewhich is the bottom edge of the cover when the latter has beenseparated, so that thebottom edge of the depending flange of the cover,which was in one piece with the body before severance, will not bejagged or outstanding or uneven.

Another important result is that I improve the appearance of the can byscoring-it internaly, which is of especial benefit in the case o a v yetprevent access of the contents of the can to said scorin and thedeterioration of Y the can body there y, b thearrangement of the collarto cover sai scoring and also. to

form a pro'ection around which the severedk cover may tto form areclosure.

' It is thought that the invention and many of its attendant advanageswill be understood from the -foregoing description, and it will beapparent that various changes may be made inthe form construction andararts without departing lfrom the spirit and) scope of the invention,or sacrificing all of its material advantages, the form hereinbeforedescribedbeing merely a referred embodiment thereof. I c aim:

1. A can, comprising a body internally scored beneath the top to providea tearin strip for removal of the top, and an interna collar coveringthe interior body scorin and secured in place by a cement band distriuted about the inner wall-of the container pripr to t epositioning ofthe collarand collected about the lower edge thereof to form"a tightseal between the can body and colla-r and to fill in spaces therebetweenafter the collar is forced into the can to assembled position.

2. The process of assembling an internal collar in an hermetic.container having internal score lines setting off a tearing stripbeneath the top which comprises distributing a band of cement about theinterior of the can body beneath the lowermost score line and nexternally lithographed can, and

forcing the collar downwardly in tight frictional contact with saidinterior surface, thus collecting a sealing ring of said cement at thelower edge of the collar and filling in irregular spaces between saidcollar and the inner surface of the can body whereby said score linesare protected from the contents of the can.

3. The proQccss of assembling an internal col'- lar in an hermeticcontainer having internal score lines setting olf a tearing stripbeneath the top, which comprises distributin a band of cement about theinner surface o the can body beneath the lowermost score line andforcing a collar having an inwardly turned edge downwardly in tightfrictional contact with the container wall whereby a sealing ring isformed beneath and behind the turne edge of said collar.

4. 1A can, comprising a bodyhavin in- Vses ternal score lines beneaththe top deinlng a -tearing strip and having an outwardly exner surfaceof the body wall beneath the score lines and collected at the edge ofsaid collar member in assembling, said cement also lilling spacesbetween the collar and can body occasioned by the formation of saidseams.

5. The combination of a can body having v its top edge outwardlyflanged, and formed on its linner surface with scored lines extend;v

ing around the body, and setting olf a tearing strip at a distance belowthe top of the body and with other scored lines at angles to thesetting-off scored lines, an interior collar fitting within the bodyopposite to said scored lines and tearing strip, said body extending 1none piece of metal past said collar and above and below the same andhaving a locked side seam arranged on the outer side of the body so asto leave the 4interior of the body smooth to be fitted by said collar,andthe ends of said collar being united by a locked seam arranged at theinner side of the collar leavmg the exterior of the collar smooth, afilm of 'cement between the collar and the body below said tearingstrip, and a anged top` end the flange of the body.

6. A diagonal or herring-bone scoring to eiect the formation of an evenedge at the bottom edge of a can reclosure, said scoring being formed onthe surface of a can body behaving its 'ange united in a double seamwith l t tween upper and lower circumferential scorings, andcombined-mth an internal collar-'- f1 ttin g tightly within the Acanbody oppositeto all of said scoring, whereby vthe tearing oi of.

the scored portion of the can body produces v an even bottom edge on theseparated upper end of said collar as a reclosure.

7. A diagonal or herring-bone scoring to effect the formation of an evenedge at the' bottom edge of a can reclosure, said scoring being formedon the inner surface of a can 5 body between upper and lowercircumferential scorings, and combined with an internal collar fittingtightly Within the can body and closure.
